ments in Dam Constructionsyof which theI Yfollowing is .a specification.

My invention relates to dam' construction and the object of my invention is to provide a hollow dam of concrete or other suitable material of like nature which can be molded,

and to provide a deck which is preferably` formed integra-l with the buttresses and which is reinforced with metalA rods ex tending longitudinally in such a manner as to form a cantaliver construction by arranging a series of upper and lower rods, one series extending from buttress to buttress within the deck and he'other series extending across the buttr sses and above the ends of the 'lower rods. A.furtl1er series of rods may be used extending from the bottom to the topv of the -deck and preferably located about half way between the upper and lower surfaces of the 'deckfand between the buttresses only, the object being to strengthen the deckto .a suiiicient degree to 'form a safe structure with as few rods -as possible. Corbels may be used to further strengthen and support the deck and by rods may be reduced. l

Referring to the drawings which form a their use the length of thelower series of' part of this specification, Figure 1 is a cross sectional view of my dam taken on line {1c-w of Fig. 3 and on a reduced scale. Fig.

2 is a plan. view of a portion of the deck.

shown partly in section to disclose the strengthening rods. Fig. 3 is a longitudinal-sectional view of a portion of the dam,

the corbel construction is em'bodied.

4 is an exterior view of a portion of the dam on a reduced scale rfrom Fig. 3 fromjthe down-stream side. Fig. 5 is, a rear sectional view of a dam constructed without theiuse of corbels. f

A, indicates the buttresses which extend Vpractically in' alinement with the flow of the stream and may rest Ona natural or Y artificial foundation. In the drawings they are shown as resting directly on the earth.

Patented Dees, 1911.

A indicate corbels which arelocated on each side of the buttresses at their tops, and

B indicates the deck which extends at an angle to the base as shown and is usually formed integral with the buttressesand corbels.

Embedded 'in the deck betweenQ-he but? tresses and extending from the bot'tom'to the' top of the dam are4 rods etc., the number depending on the'weight of water to be supported and Athe distanc'e'the buttresses are spaced apart, the proper y number and sizebeing determinedby 'anengineer in this line.

Located below the rods C-lC--Cketd 'are cross rods D-D etc. which extend from i 'corbel to corbel across'the spaces between* the buttresses, and extending across the but.-

tresses and corbels are rods E-E etc. the

them as illustrated in Figs. f1.l

the buttresses are spaced apart the same distance as'shown in Fig. 3, but

the corbels are omitted and' therefore [the lower rods are made longer to extendto 'or nearly to the buttresses and the upper rods f are l also made longer lto extend vfarther across the space between the buttresses to support the deck. l Y
